Distributional ecology of Andes hantavirus: a macroecological approach
(2018-06-22)Abstract Background Hantavirus pulmonary syndrome (HPS) is an infection endemic in Chile and Argentina, caused by Andes hantavirus (ANDV). The rodent Oligoryzomys longicaudatus ... -
A comparison between traditional and measurement-error growth models for weakfish Cynoscion regalis
(PeerJ, 2016-09-21)Inferring growth for aquatic species is dependent upon accurate descriptions of age-length relationships, which may be degraded by measurement error in observed ages. Ageing error arises from biased and/or imprecise age ... -
Senescence and carryover effects of reproductive performance influence migration, condition, and breeding propensity in a small shorebird
(Wiley, 2017-11-15)Breeding propensity, the probability that an animal will attempt to breed each year, is perhaps the least understood demographic process influencing annual fecundity. Breeding propensity is ecologically complex, as ... -
Land Cover Change in Northern Botswana: The Influence of Climate, Fire, and Elephants on Semi-Arid Savanna Woodlands
(MDPI, 2017-10-25)Complex couplings and feedback among climate, fire, and herbivory drive short- and long-term patterns of land cover change (LCC) in savanna ecosystems. However, understanding of spatial and temporal LCC patterns in these ... -
Greywater Disposal Practices in Northern Botswana—The Silent Spring?
(MDPI, 2015-11-13)Disposal of greywater is a neglected challenge facing rapidly growing human populations. Here, we define greywater as wastewater that originates from household activities (e.g., washing dishes, bathing, and laundry) but ... -
Climate Change is Likely to Worsen the Public Health Threat of Diarrheal Disease in Botswana
(MDPI, 2013-03-26)Diarrheal disease is an important health challenge, accounting for the majority of childhood deaths globally. Climate change is expected to increase the global burden of diarrheal disease but little is known regarding ... -
Fire-mediated foraging trade-offs in white-tailed deer
(Wiley, 2017-03-14)Predation risk can induce individual prey to express behavioral, physiological, and morphological traits that can influence population-level processes. Maternal care is an intuitive link between predator-mediated traits ... -
Context-dependent outcomes in a reproductive mutualism between two freshwater fish species
(Wiley, 2016-01-25)1 The development of encompassing general models of ecology is precluded by underrepresentation of certain taxa and systems. Models predicting contextdependent outcomes of biotic interactions have been tested using plants ... -
Hindcasting Historical Breeding Conditions for an Endangered Salamander in Ephemeral Wetlands of the Southeastern USA: Implications of Climate Change
(PLOS, 2016-02-24)The hydroperiod of ephemeral wetlands is often the most important characteristic determining amphibian breeding success, especially for species with long development times. In mesic and wet pine flatwoods of the southeastern ... -
Spatiotemporal Variation and the Role of Wildlife in Seasonal Water Quality Declines in the Chobe River, Botswana
(PLOS, 2015-10-13)Sustainable management of dryland river systems is often complicated by extreme variability of precipitation in time and space, especially across large catchment areas. Understanding regional water quality changes in ... -

Prevalence of Ingested Fish Hooks in Freshwater Turtles from Five Rivers in the Southeastern United States
(PLoS, 2014-03-12)Freshwater turtles may ingest baited fish hooks because many are opportunistic scavengers. Although the ingestion of fish hooks is known to be a source of mortality in multiple vertebrate groups, the prevalence of hook ... -
Gray-bellied Hawk (Accipiter Poliogaster) Observed Feeding on a Tinamou in Yasuni Biosphere Reserve, Ecuador
(Raptor Research Foundation, 2013)The Gray-bellied Hawk (Accipiter poliogaster) is one of the least studied birds of prey in the neotropics. Its geographical range in South America is from northern Colombia, east to southern Venezuela and the Guianas, south ... -
Correlation of Cere Color with Intra- and Interspecific Agonistic Interactions of Crested Caracaras
(Raptor Research Foundation, 2014)Bright coloration in birds is an important indicator of individual quality often used in social displays. Structural, carotenoid-, and melanin-based colors are long-lasting, widespread, and widely studied. Hemoglobin-based ... -
Return Rates of Aluminum Versus Plastic Leg Bands from Electrocuted Harris's Hawks (Parabuteo Unicinctus)
(Raptor Research Foundation, 2009)Ecological research programs investigating dispersal, migration, habitat selection, social structure, survival, reproductive success, and population size depend on the ability to identify individual study animals on multiple ... -
Preventing Raptor Electrocutions in an Urban Environment
(Raptor Research Foundation, 2007)Electrocution of raptors on poles supporting overhead electric lines is a cause of concern in the United States. Techniques for modifying (i.e., retrofitting) potentially lethal poles to reduce electrocutions have been ... -
Electric Shock Injuries in a Harris's Hawk Population
(Raptor Research Foundation, 2006)Electrocution may be an important agent of mortality in many raptor populations, and has been implicated as a contributing factor in the endangerment of some species. In Tucson, Arizona U.S.A. the electrocution of Harris's ... -
Nesting and Perching Habitat Use of the Madagascar Fish-Eagle
(Raptor Research Foundation, 2002)We documented Madagascar Fish-Eagle (Haliaeetus vociferoides) nest and perch use on lakes and rivers and compared parameters of used trees to unused reference trees. Nest and perch trees were broader and taller, had more ... -
Subordinate Males Sire Offspring in Madagascar Fish-eagle (Haliaeetus Vociferoides) Polyandrous Breeding Groups
(Raptor Research Foundation, 2002)The island endemic Madagascar Fish-Eagle (Haliaeetus vociferoides) is one of the most endangered birds of prey. Certain populations in west-central Madagascar sometimes exhibit a third, and sometimes a fourth, adult involved ... -
Ospreys Use Bald Eagle Nests in Chesapeake Bay Area
(Raptor Research Foundation, 1993)Ospreys (Pandion haliaetus) and Bald Eagles (Haliaeetus leucocephalus) share similar breeding habitat in the Chesapeake Bay area and elsewhere. The nests of these species are similar in size and appearance. Ospreys typically ...
